Bell Moto-9 Flex Pro Circuit Helmet Videos

Bell Moto 9 Carbon Flex Pro Circuit / Monster Energy Helmet

The Bell Moto-9 Flex Helmet introduces an innovative protective technology to Bell's flagship dirt helmet. Featuring a first-of-its-kind three layer impact liner, the Bell Moto 9 Flex Helmet provides impact protection through varying methods for specific impact speeds. This "Progressive Layering Technology" has been developed to manage energy from three potential impact scenarios - low, mid and high. The three layer system consists of (EPO) Expanded Polyolefin which works hand-in-hand with the traditional (EPS) Expanded Polystyrene and (EPP) Expanded Polypropylene.

In addition to this leap forward in terms of protection, the three layer system also provides an adaptive fit as the segmented construction automatically conforms to a rider's head for a better fit and more predictable energy management.
